Specification of Letters Patent.

Patented Aug. 29, 1905.

Applicat fln filed May 6,1905- Serial No. 259,109.

(all whom it may concern;

Be it known that I, JOHN WESLEY N EFF, a citizen of the United States,and a resident of Morgantown, in the county of Monongalia and State ofWest Virginia, have invented a new and Improved Transom-Lifter, of whichthe following is a specification.

My invention relates to means for working or lifting transoms.

The object had in view is to provide means and devices adapted for thepurpose stated which may not only be cheaply manufactured, but simple inconstruction and effective for easy working of pivoted or swingingtransoms and windows in general having similar modes of attachment totheir support.

The invention consists of the special construction, arrangement, andcombination of parts shown by the accompanying drawings, hereinafterfully described, and definitely pointed out in the claim.

In the drawings, Figure 1 is a view illustrating my invention in sideelevation and showing it applied to afragmentary support. Fig. 2 is afront elevation, part broken away, the view showing a portion of atransom and its frame. .Fig. 3 is a central transverse sectional viewtaken through the combined sprocket and gear wheel or traveler, and Fig.4 is a perspective view illustrating one form of hook device that may beemployed in the make-up of my improved lifting devices.

In the practice of my invention I employ a curved arm or rack A, havingcogs or rackteeth B on its upper side, a suitable base C, providing anattaching-base to the transom or window frame D and constructed hookedor upwardly curved at its free end, as indicated at E.

For fixed attachment to the transom or window I provide an arm or postF, having a lateral projection or journal G at its outer or free end. Onthe journal I arrange my improved traveler H. The traveler is designedto freely rotate on the journal G. It is constructed with a drumlikesprocketwheel I, having a reduced gear-wheel J on its inner side. Thegear and sprocket wheels are preferably constructed in one piece andformed as best shown in Fig. 3.

It is obvious that the sprocket-wheel teeth should be adapted for freemesh with the teeth B on the rack-arm A and that the latters hooked orcurved outer end E should provide a stop against downward rolling actionof the gear-wheel on the rack-arm and also afford retaining-supporttherefor with the transom or window held at open position, as will beunderstood upon reference to Fig. 1 of my drawings.

In connection with the drum or sprocketwheel I, I employ a link chain K,which may be endless, as illustrated in Fig. 2, or have free ends L L,as shown by Fig. 1. For holding the chain K, I employ a device M, havinghooked points h M adapted to be secured Within easy reach on the transomor window frame D. Obviously the chain may be lengthened, extendingupward from a lower floor to a transom or window located-at a floor twoor more floors above, and can be used on right or left of door, alsooperated to open up or down.

The construction of my invention will be understood from the abovedescription. In its use, supposing the transom. or window is closed andlockedclosed by engagement of one of the links in the L side or portionof the chain K with one hooked point M on the fixed device M and itshould be desired to open the transom or window upon disengagement ofthis side of the chain it is obvious that by gravity the gearwheel Jwill roll down the rack-bar A to stopped position in the curved end E ofthe rack-bar. The transom or window may be secured at open position byengagement of one link in the L portion or side of the chain Kwith thehooked point M on the fixed device M.

To raise or close the transom or window, it becomes necessary simply todisengage the L side of the chain K and pull on its L side or portion.This action will, through engage ment of the chain-links with thesprocketwheel teeth, effect a rolling operation of the sprocket-wheel.up the rack-bar A and closure of the transom or Window and in whichposition it may bev secured by engagement of a link in the L side orportion of the chain K with the hooked point M, of the fixed device M.

Having thus described my invention, what I claim as new, and desire'tosecure by Letters Patent, is

The combination in a transom-lifter, of a projecting arm, having one endadapted for attachment to a fixed support, the arm being fashioned intoa downward curve, from sprocket and gear Wheels, a link chain arrangedon the teeth of the sprocket-Wheel, and a device located below thetransom, adapted for engagement with the chain, for 15 holding thetransom-sash, as adjusted, substantially as described.

JOHN WESLEY NEFF.
